Title: Magneto-optic recorder
Inventor: HERARUDO EDOUARUDO FUAN ROSUMA
IPC: G11B11/105
Filed: 1989-05-09
Abstract: PURPOSE: To reduce the heat consumption of a coil, etc., by subjecting a radiation beam to pulse modulation, energizing a coil with energizing current pulses, adequately determining the phase relation between the radiation pulses and the energizing current pulses and nearly cooling the heated part of a recording layer during the generation of the energizing current pulses. CONSTITUTION: The radiation beam 9 is subjected to pulse modulation. The coil 12 is energized by the energizing current pulses of first and second polarities. The phase relation between the radiation pulses and the energizing current pulses is adequately determined. The heated parts of the magneto-optical recording layer 2 are nearly cooled during the generation of the energizing current pulses. Particularly at the time of supplying radiation energy in the form of pulses, the temp. passing the recording layer 2 is so regulated as to fall down nearly to the ambient temp. during the time interval between the radiation pulses. Then, a magnetic field is generated only during the short time when the heated parts are cooled by the radiation pulses. As a result, the coil 12 is merely necessitated to be energized and the heat consumption is reduced.
